Something that felt like hiccups

Margaret
So the other evening, I started having this feeling as if the baby was having hiccups. The thing is I'm only 12 weeks 5 days. And the feeling was right under my right rib. I know my uterus isn't even that big yet. So what was it??? It started about 7 ish and lasted until I finally fell asleep, at about 11:30. Like a butterfly caught in my ribs:)
